aspect oriented programming spring

Implement AOP programming using spring annotations and XMLTo implement the AOP programming annotation method, follow these steps: 1) Introduce jar files related to aop first (excellent aspectj aop components) Spring-aop-3.2.5.RELEASE.jar [spring3.2 source code] Aopalliance. jar [spring2.5 source code/lib/aopalliance] A

Prerequisites :Import the jar required for AOP:Aspectjweaver.jar and Aspectjrt.jar and Cglib-nodep-2.1_3.jarnamespaces required for joining AOP:xmlns:aop="http://www.springframework.org/schema/aop" http:// WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP http://www.springframework.org/schema/aop/spring-aop-2.5.xsdSpring provides two ways to use facets:Based on annotation and XML-based methods.development of AOP based on annotations :Premise:Precede with an AO

AOP is the Aspect oriented program for slicing. In the AOP thought, the function is divided into the core business function and the periphery function.The so-called core business, such as landing, adding data, deleting data is called the core business.The so-called peripheral functions, such as performance statistics, logging, transaction management and so on.The perimeter function is defined as a slice in

Annotated way to implement AOP programming annotation method steps:1 first introduce AOP-related jar files (AspectJ AOP excellent components)Spring-aop-3.2.5.release.jar "spring3.2 Source"Aopalliance.jar "spring2.5 Source/lib/aopalliance"Aspectjweaver.jar " spring2.5 Source Code /LIB/ASPECTJ "or" Aspectj-1.8.2\lib "Aspectjrt.jar " spring2.5 Source Code /LIB/ASPECTJ "or" Aspectj-1.8.2\lib "Note : Use the spr

AOP- oriented tangent programming in the daily development, the business logic is defined under a special service package, and the implementation is defined in the impl package under the service package.Service Interfaces to Ixxxservice form, and service realization is xxxservice, this is the protocol designsteps:1.e:\users\workspaces\kmwalletapp\spring\aop\test

First, Introduction:The ASPECTJ framework not only implements aspect-oriented programming, but also supports annotations, which spring introduces into its own specifications.Second, need to understand: ASPECTJ is an AOP framework based on the Java language Support for ASPECTJ pointcut expressions after spring2

First, it should be understood that AOP is a programming paradigm and a programming idea that is not related to specific computer programming languages, so it is not just Java, but other programming languages like. NET have AOP implementations. The idea of AOP is to separate the general logic from the business logic.Th

First defineA slice class@Aspect @componentUse the above annotations to indicate that the class is a slice classAnd customize two methods in the Slice class, respectively, after executing thepublic void before (Joinpoint jp) { ... } public void after (Joinpoint jp) { ... }Inject the class in the spring configuration fileThen configure the slice program with AOPSlice interception Handle

What exactly is AOP? AOP is the abbreviation of Aspect oriented programming, meaning: face-oriented programming (also called aspect-oriented), through the precompilation and runtime dy
